NRF51822 ble remote

[jaras]

I try to build a BLE remote control with some buttons and a bare nrf51822 chip running on battery. It's a pretty basic setup setup and I wonder if there is a code example to start with? So far I only found examples that are based on a existing eval board but on my bench I got the chip directly connected to buttons and so far I can't figure out how to get it going.

Hi,

The nRF5 SDK 12.3.0 (which is the latest with support for the nRF51) contains a number of examples, and those target our development boards. But you can modify this to fit your board, or by not using the BSP library (essentially stripping away any bsp_ related code in the example).

I don't know that kid of remote control you are trying to make, but if it for instance is a HID type of remote (that will send a button press), then you can take a look at the HID Keyboard Application.

Thankyou so much. So for trying the examples from the SDK, would you suggest using Segger Embedded Studio or should I aim för Keil? I see some articles about SES that says the projects need conversion from Keil to SES before they link..

Hi,

You are right that there are no Segger Embedded Studio projects in SDK 12.3.0. So you would have to convert the project if you were to use that. If you want a easy to use IDE that works out of the box with SDK 12.3.0 examples, that would be Keil. There are also IAR projects, and there are Makefiles. But for the latter debugging is a bit more complicated, particularly if you are not used to GDB.

Alright, your support is very useful and I got Keil installed and I also found the SDK and examples. Also found out how to setup the custom board. Great. Now only the problem that it's limited so I can't use the hids_keyboard or any other remote control. This is just for a small educational learning experiment so no business is involved. Any help to make progress is appreciated. If preferred you can send me a private message. Thx

Hi,

I see. If obtaining a Keil license is not an option, then I would suggest that you convert the relevant example projects to SES projects as described under Importing Keil projects.
